convert String to Clob and vice versa in Hibernate

Question

    public Clob getDataXML() {
       return dataXML;
    }

    p         


        

Answer 1

The limitation of 64000 characters is on the database side when you declare the XML column as VARCHAR (and not on Java String), so as long as your column XML is a CLOB, it should work.

Excerpt from working code:

Entity:

private String xml;

SQL (ORACLE):

XML       CLOB,

Hibernate mapping:

If you want to store the XML as a file, then you should rather use BLOBs as shown below :

Entity:

private byte[] xmlFile;

SQL (ORACLE):

XML       BLOB,
